Kinematics of Rotational Motion

1. The problem statement, all variables and given/known data
A turntable that is initially at rest is set in
motion with a constant angular acceleration
α.
What is the magnitude of the angular ve-
locity of the turntable after it has made one
complete revolution?

2. Relevant equations
w(omega)^2 = w(omegeInitial)^2 +2α(delta)θ

3. The attempt at a solution
So then I used that because one revolution is equal to 2pi, I said w = sqrt. (4piα).
It is multiple choice and that is not one of the choices.
Here are the choices:
1. k~ωk = 2 π α
2. k~ωk = √2 π α
3. k~ωk = 2 α
4. k~ωk = 2√π α
5. k~ωk = √2 α
6. k~ωk = 4 π α
What am I doing wrong? Sorry if it is tough to read.
